Luminosity as function of absolute magnitude for all the wavebands listed in Table 5. Open diamonds represent the photometry of GJ 1214. The color asterisks represent the BT-Settl-2010 values, and the color dotted lines the linear interpolations between them. The dashed line indicates the mean bolometric luminosity estimated using all the photometry (log   (L/L_⊙) =  −2.57). The dotted-dashed line indicates the mean luminosity with only the BVRI photometry (log   (L/L_⊙) =  −2.73), and the 3 dotted-dashed line the adopted mean luminosity for GJ 1214, derived using only the JHK_sW1W1 absolute magnitudes (log   (L/L_⊙) =  −2.44). The lowest bolometric luminosity corresponds to the I magnitude, where the SED is very steep.
